Abstract (en)

Data communication system comprising communication units and at least one public Voice and/or Data Switch for establishing at least a first communication link between a first communication unit of the data communication system and a second communication unit of the data communication system, wherein the data communication system is arranged such that at least one third communication unit of the data communication system can break-in into the first communication link. Call scenario: Caller A calls caller B and a call is set up between A and B. If a caller C now rings A, caller C can, using a previously defined PIN code, activate an override feature resulting in two call situations: 1)conference call between the parties A, B and C 2)one-on-one call between the parties A and C. Avoids call waiting queue for certain privileged callers which have previously defined PIN codes by the called subscriber. <IMAGE>
